GUN.

Specification of Letters Patent.

Application filed November 21, 1910. Serial No. 593,311.

axis of the barrel, that is at the forehead, to

provide an additional but removable stock bifurated so as to adapt it toengage against each shoulder of the userinY order to provide threesupports against the body of the user for the rear of the gun and withthe members'of such bfurcated stock adapted to be folded together tocomprise in eEect a single stock to which there is pivotally connected aforward portion comprising substantially a pistol grip. `The entirestock may preferably also be detachably connected to the gun.

Another object is to provide means wheres by the binocular telescopesare adjustable to the different distances between the eyes of differentusers and in which also the mechanism for regulating the angle of theelevation of the gun for distances is Controlled by the focusing screwof the telescope.

In guns as usually heretofore constructed there 1s provided a stockcomprising ashoulder piece adapted to rest against the shoulder of theuser to steady and support the gun in use and to transmit the recoilofthe I have found this method of construction objectionable on accountof theslight swinging of the gun at the recoil, the axis of the gun andthe line of direction of the recoilbeing considerably removed from thepoint of support of the gun at the shoulder.

I have-found that, in a properlyproportioned gun fired with the propercharge, the recoil resulting from the firing of the gun may be sustainedat the forehead and justl above the eyes of the user, thus rc'ducin'gto' a minimum the distance between the point sustaining the recoil andthe 'axis of the gun.

As usually constructed guns with telescopic sights areprovided with asingle tele- @nope for use with one eye only so located as to requirethe user of the gun to assume an unnatural position in the act of firingthe gun. I have found that this ,objectionable feature may be overcomeby providing two telescopes or what is called a binocular telescopelocated slightly beneath the barrel of the gun and adapted to line upopposite the eyes of the user of the gun and along the line of vision insighting the gun and in connection therewith I employ means whereby uponthe operation of the focusing screw of the telescopes the elevation ofthe gun is automatically adjusted to the proper range .p

for which thetelescopes are focused.

Another feature of my present invention comprises an auxiliary stockfo'r the gun which is bifurcated and adapted to vengage against eachshoulder of the user at substantially the usual -point thus providingthree points of support for the gun and affording increased steadinessin the act ofl firing. I rovide means whereby the bifurcated sho derrest or stock may be folded together so as to present one or a singlestock to facilitate carryingand transportation and also to adapt the gunto use at short range and I also provide for such short range use aivota'l connection between the pistol grip orming part ofthe stock andthe rear portion of the stock whereby the angle of the direction of thebarrel relative to the main direction ofthe stock may be readily*adjusted within amode'rate range. The accompanying drawingsillustrating.

a preferred embodiment Vof my invention are as follows:Y

Figure 1 is a right hand side view of the gun` showing therefore onlythe right hand forehead engaging piece and telescope as they arearrangedv for use andV enlarged view ofthe gun from the rear but withthe grip member and the stock removed, while Fig. 4 shows in a similarlyenlarged view, the rear telescope and gun supporting member A1 invertical section taken along the line -Jy of Fig. V3, and a part of theconnecting member S is `also shown in se'ction. The'breech of the gunisshown i'n this gure in side view, while in this gure the members forengaging the'forehead are v enlarged transverse sectional view ofthe,thetrigg'er support-and actuating mecha- Vnism and, in this figure, apart ofthe conbeneath the fulcrum of the triggerof the gun removed. Fig.5 is a plan'view of the gun with the .stock removed. Fig. 6 is anenlarged transverse sectional view of one of the telescope members takenalong the lineI 1y1,of Fig. 5, while Fig. 7 is a similarly parts takenalong the line'Z--yZ-'of Fig. 5 as 'viewed from the right. Fig. 8- is anenlarged plan view of the central part'of the gun showing thefocusingmechanism and necting bar S is also seen comprising the supportfor the above mentioned mechanisms. y

Similar parts are designated by 'similar reference characters throughoutthe several figures of the drawings..

Referring to the drawings. Forcoperatively connecting the telescopes Tand body, comprising the breechfan-d barrel, of the gun I provide front'and rear supporting or bracket members A 'and A1 respectively, connectedby a longitudinali-y extending cross piece S secured thereto asindicated in Figs. l, 3, 4, 5 and 7. This connecting piece S is curveddownwardly toward its rear end as indicated in Fig: l ,andis' `widened.ont

as seen. The forward bracket A, as seen in Fig. 7, has a U shapedopening at its upper edge to provide a pivotal support for the barrel ofthe gun, the barrel of the gun B being pivotally supported therein uponthe screws b threaded through the lugs a.- The-breech B1 of the gun, asseen in Figs. 3 and 4, is shouldered and in the upper sidel of theshort'rearward extension formed at the shoulder there is vseated a.coiled spring s, theupper end of which is seated in a recess in thecross piece a of the rear bracket A1, the operation of the spring stending normally to hold the breech of the gun downwardly in itslowermost position against the bottom of the opening therefor in thebracket A1.

The body of the gun is therefore pivotally mounted in a frame comprisingthe bracketsA A and A1 and the connecting `bar` S. Through each ofthesel brackets A and A1 there are formed circular openings forreceiving the split or opened eccentrica Call exactly alike and' eachprovided with a knurled head c and each rotatable in the cor'-responding opening in the brackets A and A1. Through these bracketsbeneath the openings for theeccentrics C are provided openings extendingdownwardly and bounded by lugs a1 and a3 through which suitable setscrews b1 extend for clamping',- in the manner clearly indicated, theeccentrics C inany desired position of angular adjustment. Through eachof these eccentrica C there is eccentrically bored a hole for receivingsimilar eccentrics D, each of which r is also provided with a knurledhead d to facilitate their angular adjustment. The eccentricities oftheeccentrics C and D are made equal. A

The inner eccentric rings D are bored out eccentrically for receivingthe outer teiesope tubes t carrying the eye pieces e. Within these tubesz5 inner tubes t1 are made to slide freely but not loosely, such tubest1 carrying the enlargements e1 containing the usual object glasses. y

Any suitable construction may be made use of for preventing a lon'tudinal movement of the tubes t. throug the cam rings D and also forpreventing a similar movement vof the cam rings D within the cam rings Cand also of the rings C within the brackets A and A1, such, forinstance, as a grooved-construction, of one of each pair of suchcooperating members adapted to receive a corresponding ridge or tongueon the other member, such constructions being well known in the art nofurther description thereof is believed to be necessary herein.

The connecting bar S carries a plate 0 having a bracket o within whichthere is revolubly mounted the-rear bearing of a screw N1 the other endof which is supported in a bearing o1 carried by the plate O while thesebearings 0 and 01 are such as to prevent endwise movement of the screwN1. 0n the rear end of the screw N1 is seen a beveled gear ,q1-meshingwith a similar beveled gear g carried by the hub of the focus. ing screwG which latter is revolubly supported on a stud extending laterally, tothe right, with reference to the user of the gun, .from the bracket o.The brackets o and 01 maybe cast integrallyv with the plate O whiehfissecured to the upper side of the connecting bar S. Threaded over thisscrew -N1 1s seen a nut N having laterally extending bifurcated ears nengaging into the bifu-rcated lugs or ears n1 carried by the innertubesftl' vof the telescopes, the construction beingsuc'h as clearlyshown as to permit .'ofl'the'adjustment to and from each other of thetelescopes without eii'ecting thelongitudinal adjustment of the tube t.The ears or lugs nl are carried 0n arrnssecured to the inner tubes t1-e'xtending outwardly through suitable longitudinally extending slotstherefor in the outer tubes't. lBy the operation of the milled head Gthe focusing of the telescope is effected in the usual manner while theadjustment of the distances between the telescopes to compensate for thedifferent distances between the eyes of different users is effected byoperating the eccentrics C and D in opposite directions by means of themilled heads thereon c and (l, after, of course, having first unscrewedthe screws 1' engaging through the lugs a1 and a".

Un the breech piece B1, on the right hand side thereof, is pivotallysupported at r2, an`

adjustable arm R held in any desired position of adjustment by means ofthe thumb screw r1 threaded into the breach B1 and engaging through aslot therefor in an upwardly turned arm y' formed onthe rear end of thelever R while coperating with this lever R there is seen a roller Urevolubly mounted on a stud on the inner edge of the right handtelescope tube t1 and near its rearward end and extending outwardlythrough a slot therefor in the outer tube t,

the action being such that `the movement to" the rear of the tube t1permits the spring s .to force the breech of the gun downwardly whilea'forward movement of such tube t1 operates to raise the breech of thegun against the action of the spring s.

From the construction thus far explained, it will be readily understoodthat the focusing of the telescope actuates the mechanism for raisingand'lowering the gun for diiferl'ent ranges in accordance with the focusin the telescope and I have found it desirable to provide an adjustablerelation between these mechanisms as already explained by means of thepivotally supported lever R and the means described for securing thesame in any desired position of angular adjustment.

At m1 is seen a substitute for the usual trigger of the gun engagingthrough an opening therefor in the plate S and at its lower endarticulating with the link M, the forward end of which articulates withthe lower end of the auxiliary trigger J pivotally supported upon a studsecured in the bracket jl carried by the plate S as seen in Fig. 8, suchstud engaging through the barrel or body j located at the center of the.trigger J. e v

I have sometimes found it desirable to provide a pistol grip, such asseen in Fig. 1 at P, having forwardly and rearwardly eX- tending membersp2 and p3 adapted to be secured to the under side ofthe connecting bar Sand provided with an upwardly extending ear 79 formed integrallytherewith and upon which is pivotally supported a second trig- 'germember p1 provided with a laterally extending pin fm engaging in a slottherefor in the under Side of the connecting link M and near its forwardend whereby the gun may be fired by either the operation of the triggerJ or the operation of the trigger 791. l

The rear bracket A1 carries laterally extending arms l, on itsupper edgeterminating in curved plates H adapted to engage against the forehead ofthe user ofA the gun just above the eyes. These members H may beprovided with suitable pads to engage against the forehead.

I have sometimes found it desirable to the gun comprising a bifurcatedstock piece consisting of two main members V hinged as 'seen at 7c to acommon connecting piece K which is bifurcated to engage over the eX-tension of the pistol grip P at .its lower end and is pivotally securedthereto by means of the screw L provided with a thumb nut Z to permit ofany desired angular adjustment, within a. moderate range, of the membersVv and the pistol grip P. To each'member V, and on its under side, ispivotally connected one end of a link o such links being pivotallyconnected at their other ends by means of a-bolt o1 and having a thumbnut o2 to permit of the angular adjustment of the members V and thesecuring' of them in any desired position of such adjustment to providefor different widths between the shoulders of the users of the gun. Thepivotal connection between the grip member P and the member K providesfor different adjustments of the gun for different distances between theeye and shoulder of the user and by this means provision is also made,when the members V are folded together, for quick firing at short rangeat objects considerably above or below the eyeof the` user of the gunwithout'necessitating that the user assume an unnatural position in thefiring of Y the gun.

In using my gun the telescopes are adjusted to the distances between theeyes in the manner already described, by operatingV the milled heads cand al and theproper adjustment is given to the lever R then by focusingthe telescope by means of the milled head G, the desired elevation ofthe gun is given simultaneously with the focusing ,of the telescopesupon the mark or obj ect aimed at and the gun may be held by the handsof the user against the forehead, Iin a position 'substantially such asindicated in Fig. 1, without the use of either the pistol grip or thedetachable stock ,pivotally connected thereto the firing being effectedby the operation of the trigger J in the manner already explained; when,however, it is de- -sired to make use of the auxiliary stock and thepistol grip the same is attached and adjustment made in the manneralready described and the gun may then be fired by the trigger ph 1 Theusual front sight f1 and rear sightFA and adjusting plate therefor f maybe provided also and to permit of their use the forehead pieces Harespaoed apart as seen in Fig. 3.

It is believed from the foregoing description of the operation of theseveral features of my gun that the method of using the same issufficiently clear to call for no further explanation herein. I maymention, however, that when the gun is used without a stock it may bereadily -held and sighted .by holding the outer tubes of the telescopeand focusing the gun Very much as is done in tlie use of a field glassand after properly focusing the gun may be fired in the manner alreadydescribed.

What I claim is:

l. A rifle or like. firearm provided with binocular refractingtelescopic sighting. means'w-herein the eye piece of each te1escope isthe relatively fixed and the object glass the relatively movable memberfor adjustment in focusing, the telescopes adjustable todi'fferentdistanees between the eyes of different users, independent ofvariations in the focusing means or the elevation determining means ofthe rifle and provided also with means for determining the elevation ofthe rifle under the control of the telescopic focusing means.
